作为最有效的合成工具之一，逐层（LbL）自组装技术可以在同相或异相化合物或带相反电荷的聚电解质之间提供强非共价结合和准确组装，从而产生高度有序的纳米级结构或图案具有优异的功能和活性。它已被广泛应用于从纳米技术到医学领域的新材料和纳米结构或图案的开发。然而，LbL自组装在开发高效电催化剂、质子交换膜燃料电池（PEMFC）的特定功能化膜和超级电容器的电极材料中的应用是相对较新的现象。本文综述了LbL自组装技术在质子交换膜、Nafion膜、Pt基电催化剂、自组装碳纳米管和石墨烯等质子交换膜燃料电池关键材料的开发和合成中的应用。LbL自组装的多层纳米结构材料用于电化学超级电容器的发展的应用也将进行审查和讨论（250参考文献）。
As one of the most effective synthesis tools, layer-by-layer (LbL) self-assembly technology can provide a strong non-covalent integration and accurate assembly between homo- or hetero-phase compounds or oppositely charged polyelectrolytes, resulting in highly-ordered nanoscale structures or patterns with excellent functionalities and activities. It has been widely used in the developments of novel materials and nanostructures or patterns from nanotechnologies to medical fields. However, the application of LbL self-assembly in the development of highly efficient electrocatalysts, specific functionalized membranes for proton exchange membrane fuel cells (PEMFCs) and electrode materials for supercapacitors is a relatively new phenomenon. In this review, the application of LbL self-assembly in the development and synthesis of key materials of PEMFCs including polyelectrolyte multilayered proton-exchange membranes, methanol-blocking Nafion membranes, highly uniform and efficient Pt-based electrocatalysts, self-assembled polyelectrolyte functionalized carbon nanotubes (CNTs) and graphenes will be reviewed. The application of LbL self-assembly for the development of multilayer nanostructured materials for use in electrochemical supercapacitors will also be reviewed and discussed (250 references).
